Plastic heating duct connectors

Abstract

A connector for connecting a terminal end of a heating duct to a heating duct board, the connector including an annular cylindrical portion with an outer surface and a maximum outer diameter and a flange extending radially outwardly from the outer surface of the annular cylindrical portion. The flange has a dimension greater than the maximum diameter forming an abutment against which a lower edge of the heating duct board abuts. The flange also has at least one sleeve for receiving a zip tie. The connector includes retention means for securing the connector to the heating duct board with the heating duct board encircling the annular cylindrical portion and being in abutting engagement with the flange. The retention includes at least one zip tie mounted through the at least one sleeve of the flange and engageable in a mouth of the heating duct board to which the connector is secured.

1. A connector made of plastic for connecting a terminal end of a heating duct to a heating duct board, the connector comprising:
 at least one annular cylindrical portion with an outer surface and a maximum outer diameter; 
 a flange extending radially outwardly from the outer surface of the annular cylindrical portion, the flange having a dimension greater than the maximum diameter forming an abutment against which a lower edge of the heating duct board abuts, and having at least one rectangular sleeve for receiving a zip tie; 
 retention means for securing the connector to the heating duct board with the heating duct board encircling the annular cylindrical portion and being in abutting engagement with the flange, wherein the retention means comprises at least one zip tie, mounted through the at least one rectangular sleeve of the flange and through the flange, and engageable in a mouth of the heating duct board to which the connector is secured. 
 
     
     
       2. The connector of  claim 1  wherein the connector is made of a material selected from the group consisting of acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), liquid crystal polymer (LCP) resin and polyphenylene sulfide (PPS), polypropylene (PP) and polyethylene (PE).
